Its creators at Waseda University in Tokyo and the Japanese robotics company Tmsuk hope their two-legged creation will one day enable wheel-chair users to climb up and down stairs and assi

9、st the movement of heavy goods over uneven terrain.The bakery-powered robot, code-named WL-16, is essentially an aluminium (铝) chair mounted on two sets of telescopic (套迭的, 伸缩的)poles. The poles are bolted to flat plates which act as feet. WL-16 uses 12 actuators to move forwards, backwards and sidew

10、ays while carrying an adult weighing up to 60 kilograms(130 pounds). The robot can adjust its posture and walk smoothly even if the person it is carrying shifts in the chair. At present it can only step up or down a few millimeters, but the team plans to make it capable of dealing with a normal flig

11、ht of stairs.“I believe this bipedal robot, which I prefer to call a two-legged walking chair rather than a wheel-chair, will eventually enable people to go up and down the stairs,“ said Atsuo Takanishi, from Waseda University.“We have had strong robots for some time but usually they have been manip

12、ulators, they have not been geared to carrying people around,“ says Ron Arkin, at the Georgia Institute of Technology and robotics consultant for Sony. “But I dont know how safe and how user-friendly WL-16 is.“Tmsuk chief execut, ive Yoichi Takamoto argues that bipedal or multi-legged robots will be

13、 more useful than so-called “caterpillar models“ for moving over uneven ground.WL-16s normal walking stride measures 30 centimetres, but it can stretch its legs to 136 cm apart, The prototype is currently radio-controlled, but the research team plans to equip it with a stick-like controller for the

The World

30、 Health Organization says preventable injuries and deaths from medical operations are a growing concern.Experts estimate that at least one million people die every year because of complications from surgical treatments. The W. H. O. says studies suggest that about half of these problems may be preve

31、ntable.

He helped develop the Safe Surgery Saves Lives program. Doctor Gawande and other researchers stud

32、ied records from fifty-six countries.In two thousand four, surgical complications in developed countries led to death in less than one percent of cases. In developing countries, the rate was five to ten percent. Complications can happen during an operation or after. For example, an infection might d

33、evelop after an operation.More than two hundred medical societies and health ministries have joined in the effort to make surgery safer. The new list is similar to what airplane pilots use before flying.One member of the surgical team is responsible for the checklist. The first questions are asked b

34、efore the patient receives anesthesia. The very first step is to confirm the patients identity and the operation to be performed.More questions are asked before the first cut. All members of the team are supposed to identify themselves by name and job. Another step is to confirm whether the patient

35、was given antibiotic drugs within the last hour to prevent infection.The third and final part of the checklist is completed before the patient leaves the operating room. For example, surgical equipment is counted to make sure nothing unnecessary stays in the patient.At eight locations worldwide, the

36、se actions were being done only thirty-six percent of the time. But the W. H. O. says use of the list increased that to sixty-eight percent. Some hospitals reached almost one hundred percent.Early results from one thousand patients showed a drop in complications and deaths. Doctor Gawande says the c

A final version of the list is expected by the end of the year.（分数：15.00）(1).What is the suggested effort mentioned in this passage to prevent deaths and injuries in hospital operation?（分数：3.00）A.To reduce surgical treatments.B.To build around a new Surgic

42、es Water-ice FadeThe pictures acquired by a NASA orbiter(卫星) show white material exposed by flesh meteorite impacts fading over time-behaviour expected of ice on Mars. An onboard instrument also detected the tell-tale chemical signature of water.To date, exposed water-ice has only been seen at very

43、high latitudes. The US space agencys (NASA) recent Phoenix probe famously dug into water-ice at its“ high Arctic“ landing site. The implication, even with the small set of examples scientists now have, is that broad deposits of ice sit just below the red top-soil of Mars. “Theres a consistent pictur

44、e starting to emerge now that these broad sheets may be common on Mars,“ observed Shane Byme of the University of Arizona, a member of the team running the HiRISE camera on NASAs Mars Reconnaissance Orbiter (MRO).“The volume of water is probably comparable to the volume that we would have in the Gre

45、enland ice sheet on the Eanh-in the buried ice deposits that stretch from each pole to mid-latitudes. “MRO has produced“ earlier“ and“ later“ images at five fresh impact sites made in 2008. These were all halfway between the North Pole and the equator on Mars.The craters (环形山, 陨石坑) were small, just

46、a few metres across, gouged out by incoming space rocks that may have been no more than 10cm in size. The bright, white deposits uncovered by the impacts were seen to wither over time, something exposed water-ice cannot help but do in the low-pressure Martian atmosphere. It is bound to sublimate-to

47、tum directly from a solid into a Vapour.However, the length of time it took to fade was a good indication that the ice was very pure. Had it contained a lot of dirt mixed in with it, the ice would have sublimated much quicker, scientists said.The discoveries made by MRO are said to indicate that Mar

48、s had a more humid climate in the relatively recent past, within the last 10,000 years. Scientists suspect much of this ice came out of the atmosphere. Water vapour in the atmosphere will diffuse through the particles of the soil until it gets to a certain depth where it then freezes.The locations o

49、f the exposed ice fit with the models used to predict where ground ice might be stable, i. e. from mid up to high latitudes.“The more humid the Martian atmosphere, the more extensive the area of this stable ice. “ explained Shane Byme. “Based on the locations of these craters, we are able to say something about how much water was in the Martian atmosphere recently, and t
